5. What is Internet of things?
1. Network of objects .
2. A system to identify any kind of object.
3. From a network of interconnected
computers to a network of interconnected
objects

6. What is Internet of things?
… from communicating people (Internet)
... to communicating items …
... from 3-5 computers per person …
... to 10-25 communicating items per person …

Define: pervasive
Define: ubiquitous
Technology that will be all around us and
therefore “invisible”

13. IoT :IP Based
Thanks to IP:
• IP is versatile
• IP is scalable Internet of Things
• IP is ubiquitous

15. IoT : Standard
1% of 802.11 power easier to embed, as easy to use
IEEE 802.15.4 – The New IP Link 15

16. IoT : middleware system solution
Application
TCP/UDP 802.15.4 has a maximum frame size
of 128 bytes.
6lowpan compresses the standard
48 bytes of the IPv6 and UDP
IP/ICMP
headers down to 6 bytes.
Adaptation
Layer 6LOWPAN
MAC layer& 802.15.4
Physic layer
The position of 6LoWPAN in the network architecture

19. Security in the IoT
What do we need?
authentication of tags proof of origin of
products
authentication of readers … access control to
tag’s data/configuration
encryption … privacy
secure point to point connection – data integrity
signatures by tags/objects … mobile readers
and static tags
